[Q] How to install Google Nexus ROM on Samsung S4 GT-I9500

I am new to this stuff, so if somebody would be nice to tell me the procedure how to get the google nexus sistem on my Samsung s4. Is that possible and if yes please explain. I would like the plain nexus sistem with no fancy extra software if possible.
And where can I find the links for the correct roms, cause I've read somewhere that it is possible to brick my phone if wrong rom installed.
